You can try to reset error code in service mode, but if the error persist after clear, you need to rectify the problem and replace fault component which is fairly fixing easy to do.
The problem can be in thermistor, sub thermistor or dc controller pcb, or ... call service!
To reset error code:
while ready to copy/showing the error code:
1) Press the user mode key ( * ) on the control panel.
2) Press the 2 and 8 keys at the same time.
3) Press the user mode key ( * ).
Choose: COPIER>FUNCTION>CLEAR>ERR
Turn off and back on the copier.

what i can tell you is that there is a comunication problem between the printer board and main controller. the only suggestion i have for you is to call for service and have someone come out and check all the boards. unless you know how to remove them and try putting them back in
